    FLANGE SAFETY VALVES SERIES 355


    The series of flanged safety valve 355 captivates with its consistent concept of capacity, function and design. The high capacity of the entire series from DN 15 up to DN100 is unique in the sector of flanged safety valves.

    Using spheroidal graphite cast iron for the housing allows a particularlyinexpensive variant to be produced. This is of particular interest for applications with heating water and steam as well as lower requirements with regard to high corrosion resistance. This series can be supplied either with open or closed cap.

    Material : Spheroidal graphite cast iron
    Size : DN 15 to DN 100
    -10°C to + 350°C

    SAFETY VALVES ANGLE TYPE SERIES 652


    SAFETY VALVES ANGLE TYPE SERIES 652

    This safety valve made of gunmetal is an economical alternative to high-performance safety valves, in cases where only small blow-off capacities are required.
    The version 652mf for neutral liquids is ideal for the protection of pumps and pressure vessel systems, in cases where boiling point is never reached or if no evaporation of the media can occur.

    The version without diaphragm, type 652G is ideal for protecting small compressed air systems. Depending on the sealing material, this valve can be used for neutral, non-toxic compressible media with varying temperatures.

    Material : Gunmetal
    Size : 1/2"- 2"
    -50°C to + 200°C
    (depending on version)
    1,0 - 16 bar
